Back in August, along with many others, my desktop would freeze when I
used OpenOffice.org. The bug turned out to be in xserver and was widely
documented:
https://bugs.freedesktop.org/show_bug.cgi?id=10525
http://qa.openoffice.org/issues/show_bug.cgi?id=75578
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=395354

There's a Fedora patch at
http://cvs.fedora.redhat.com/viewcvs/devel/xorg-x11-server/xserver-1.3.0-xkb-and-loathing.patch?view=markup
Something like it was applied in Debian on Thu, 09 Aug 2007:
xorg-server (2:1.3.0.0.dfsg-12) unstable; urgency=low
[ Brice Goglin ]
* Add 51_xkb-and-loathing.diff to fix a hang in OpenOffice.org
And then promptly disabled in the Sat, 18 Aug 2007 update:
xorg-server (2:1.3.99.0-1) experimental; urgency=low
[ Julien Cristau, David Nusinow ]
+ 51_xkb-and-loathing.diff disabled for now.
I'm getting this same bug still with both the 32-bit and the 64-bit
version of OpenOffice.org, using xserver-xorg 1:7.3+8 and
xserver-xorg-core 2:1.4.1~git20071212-1.
Specifically, the bug is triggered when selecting any of the main menu
items. Cf. http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=440974
The test case below freezes X11 at 100% CPU utilization and xorg has to
be -9 killed.
What was the problem with the fix? This is a really debilitating bug; is
there a workaround? A discussion somewhere I missed? An odd
configuration on my system?
Cheers,
Dave
